The shell game that we play ... is technically called 'renormalization'. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It's surprising that the theory still hasn't been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate.

I learned very early the difference between knowing the name of something and knowing something.

We are lucky to live in an age in which we are still making discoveries.

Philosophy of science is about as useful to scientists as ornithology is to birds.

You see, I get such fun out of thinking that I don't want to destroy this most pleasant machine that makes life such a big kick.

For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

If it disagrees with experiment, it's wrong.
